The immediate practical consequence is that a ceasefire long observed under UN watch is now observed without it.
The United Nations has confirmed the end of its peacekeeping mission in Western Sahara after the Security Council failed to renew its mandate, prompting Secretary-General Antonio Guterres to warn of the risk of hostilities escalating. According to Al Jazeera, Guterres' spokesperson, Stephane Dujarric, said in a statement on Sunday that the Secretary-General "remains concerned about the security situation throughout the territory and the risk of hostilities escalating". Guterres urged all concerned to exercise maximum restraint and to refrain from actions that could further increase tensions or undermine regional stability.
The Mission for the Referendum in Western Sahara, known as MINURSO, was established in 1991 to monitor a ceasefire and prepare a referendum on the territory's future. November 1 marked the start of its "liquidation phase", with assets transported back to troop-contributing countries. The lapse follows a vote on Friday in which Washington proposed a resolution that would have extended the mission for a year, removed "referendum" from its name and made Morocco's autonomy proposal the only basis for further talks. Russia vetoed the draft despite support from 11 of the 15 council members, including France and the United Kingdom. A competing Russian resolution was then defeated, leaving the mission to expire without a new mandate.
The dispute dates to 1975, when Spain withdrew from the desert region, which Morocco has considered its territory ever since. The Polisario Front, an Algeria-backed movement acting on behalf of the Indigenous Sahrawi people, seeks an independent state called the Sahrawi Republic. The collapse of the mandate therefore removes the mechanism that has for three and a half decades separated the two sides on the ground, at a moment when the diplomatic framework around the question is itself being contested.
The reactions from the parties point to how each reads the outcome. Morocco's royal palace described the non-renewal as a "significant development" in withdrawing the Western Sahara issue from the Security Council's consideration. Algeria's Foreign Ministry expressed "deep regret", blaming what it called the "excessive bias" of the United States towards Morocco's position. The Polisario Front said it was "concerned at the deadlock in the Security Council meeting". At the council, US Ambassador Mike Waltz said it was truly unfortunate that in 2026 the veto was used to "preserve the letter R [in the Mission's name] for referendum", adding that Washington's proposal "would have moved the 50-year conflict forward" and that the status quo is unacceptable. Russia's ambassador, Vassily Nebenzia, said Moscow opposed the draft because it favoured one side, stressing that the Security Council cannot automatically predetermine matters relating to sovereignty.
Guterres said the UN stands ready to continue supporting efforts to advance dialogue and pursue a peaceful resolution of the conflict. What is not yet known is how the absence of monitors will affect conditions on the ground, whether either party will take steps that alter the current lines, and whether the council will return to the file in any form. The immediate practical consequence is that a ceasefire long observed under UN watch is now observed without it.
